Subject: [RFC] parser: add const to parser token table

Hi,

Any objections to the following patch? If not I'll send it on to Linus.

This patch adds a "const" to the parser token table. I've done an
allmodconfig build to see if this produces any warnings/failures and the
patch includes a fix for the only warning that was produced.
